Single Driver Site

In case anyone hasn't noticed / hasn't run across it before, James has managed to get his site back up & running after a ~12 - 18 month hiatus, caused by some loathsome little reptile attacking things.

New address http://www.fullrangedriver.com/singledriver/

Some of it's a little dated now, esp. WRT TQWT design[s] (strictly speaking conical horns) but it's still good to see it back again as there's some useful information there, plus, it still serves as a source of inspiration.

Hi Scott

Thanks for pointing this out. Gotta love those Hedlunds.

Flash from the past

'specially fun to revisit Terry Cain's original BIB project (heard a pair in 2001) and others that predate the application of Martin King & Ron Clark "evolutionary" work on 1/4 Wave and BLH designs that have certainly benefited the DIY community.

and some folks say there's been no significant developments in speaker design for a couple of generations

That's great news. I used to love hanging around there.

Actually, I was thinking that this time I'd carve them out of a solid block.

you mean like this?

As I read the review and manufacturer's website, this is not "layer-toned", but 2 clam-shells carved from laminated solid wood slabs.

no, our machine can't do that

Crikey.

You beat me to it Chris -I was thinking they'd be a potential candiate for translam construction at least, at one heck of a material cost of course...

and at a nominal charge out rate on our commercial CNC of $100/hr (really just to discourage the punters, but it does have significant operating overhead ), the machining time could dwarf the cost of many materials.
